assuming that（假设/如果）本身是用作条件状语的分词短语，因此可以把它视作引导条件从句的连词，相当于if 的用法。条件从句有两种情况：一种是真实语气，表示基本与事实相符；一种是虚拟语气，表示不符合或不一定符合事实。assuming that 的用法也是如此。

如对下面句子的两种不同表述：

就算你是对的，这件事也没什么我可以做的。

Assuming you're right, there's not much I can do about it. 【心里承认对方是对的，只是口头上不服气】

Assuming you were right, there were not much I could do about it. 【明知对方不对，】

就算会谈取得了进展，也未免太微不足道，且为时太晚了吧?

But assuming that the talks make progress, won't they dotoo little, too late? 【会谈可能会取得进展，但心服而口不服】

But assuming that the talks made progress, wouldn't theydo too little, too late? 【事实上会谈没有也不会取得进展】
